I have a client who was using JetBrains' TeamCity CI product. Was a clown show of vulnerabilities that allowed attackers access to internals.
Do not use their products. If you must for some reason, be sure you subscribe to critical CVEs of the products you are using and update them immediately and rotate your credentials. Ideally re-install on a fresh server. Never have the service available via the public web, it will be hacked - only use their products behind a VPN.
